To all whom it may concern:

i' Brooklyn,

Be it known that '1, NELSON F. KNOX, citizen of the United States, and resident'of in the county of Kings and State of New York, have invented certain new and useful Improvements in 'Iype-"Viriting May chines,'o:t which the following is a specification. l This invention relates to typewriting machines of the class known as type bar maand more especially to that stylein and individual hanger;Vl

One object of the invention is to provide a hanger which shall attord a wide bearing for the type bar and which is substantial in character and capable of manufactureA at small cost.

. Another object is `to so arrange the typebar hangers upon their support that they may be very compactly assembled and, that any. type bar hanger may be placed upon, removed from, or secured to said support without disturbing or interfering with any other type bar hanger.

To these and other ends, which will subsequently appear, the invention consists in certain features of construction and combinations of devices, all as will be hereinafter larged side elevati'on described and particularly pointed out in the appended claims.

In the accompanying drawings` Figure l is a vertical i'ront to rear sectional view, taken centrally of the typewriting machine to which the invention has been applied, parts ot s* id typewriting machine being omitted in tharder that the invention may be more clearly disclosed; Fig. 2 is a' front?.

elevation of the type bar hanger support or segment, a number of ,type bar hangers being shown assembled thereont Fig. 3 is an enand Fig. t an enlarged and partly sectional,

' ot' the hangers ot the forward series;y a part of the type bar also being shown; Figs.

5 and G are corresponding views of one ot the hangers ot the'rear set lor series; and Fig. 7 is van enlarged side elevation of a front hanger and a rear hanger, and parts of their type bars. as the said hangers appear when'assembled on the segment, a section of the latter also being shown.

Like parts are designated by like numerals throughout the several views, wherein- 1 indicates. .the base g of thjomachme, 2

front elevation ot one corner posts supporting the top plate 3,

which in turn sustains the carriage (not shown),

1. `Key levers 5, each provided with the usual key button 6 and restoring springA 7 'arepivoted at 8 in the rear ot the base ot the machine. Each key lever has pivoted to' 1t at 9 -a sub-lever 10, the lower part of which is formed with a slot 11 receiving a fixed tulcrum bar 12, which extends from side to side of the machine beneath the key vlevers and is supported in the base of the trame. Pivoted to the upper end of each sub-lever at 13 is the rear end of a connecting link 14, the forward end of said connecting link being pivoted at 15 to type bars 16. The

outer or type ends of the type bars are each provided with two types and are sustained in normal or rest position by a segmental rest or pad 17 supported by several arms,

. of wliiclronly'the left-hand arm 18 is shown,

the said arms extending forwardly from the support 19 to which they are attached.

The support 19, as herein shown, is of the form commonly known as a segment, and will be so described hereinafter. Although the drawings disclose a segment of the shift order, thatis, one which is bodily moved when it is desired to change from upper to lower case or the reverse, it is to be understood that the particular style of segment is immaterialA for the purposes of this invention, andlthat a stationary segment and a shiftable platen might be employedl or that neither platen nor segment should be shiftable and each type bar have but a single type, and that either of these latter constructions would still be within the scope of the invention. It is not deemed necessary to describe a mechanism for shifting the segment 19, since the invention is not concerned with this feature', any mechanism desired may be employed for the purpose, such, for example, as that used in the Monarch typewril ing machine.

,The type bar hangers which are supported or mounted upon the segment 19 and. in which the type bars 16 are pivotedrare of two forms; those of one form, that illustrated most clearly in vFigs. 3 and 4, are assembled upon the segment in` one row or series, lwhich 'is they forward row. and the hangers of tbe` other form. that illustrated mostclearly in Figs. 5 and 6, are'assembled l the latter carrying the platen 4. which 1s diagrammatically illustrated in'Fig..

upon a machine in a second row or series, that is, the rearrow or the one wherein the pivot bearings are the closer to the face of the segment. Though the form of the hangers composing these series differs somewhat, the method employed in manufactur.

lng them is preferably the same. Eachhan er 20 of the forward set or series is prearably stamped out of sheet metal, and the blank so stamped or punched out is thereafter folded or bent up so as to form two bearing walls which, with the turns 22 at the bottom of each, form a part which is substantially U-shaped in cross-section. Depending from the bottom of, and preferably centrally from, the U is a shank or stern 23 formed of two plies or folds of metal, the

continuations of said plies or folds forming the bearing walls 21, the lower end of the shankor stem 23 terminating in an eye 24 which is reamed out suiciently t'o receive the stem of a headed screw 25 by which it is secured to the segment 19. The part ofthe metal blank which is to compose the shank or stem 23 and the eye 24 is twice as wide as the art to compose the walls 21, so that when tlie hanger 20 is folded into shape the shank and eye portion is substantially twice as deep as the bearing wall portion, the former portion having a rearwardly projecting part 26, as appears most clearly in Fig. 3. The right hand ply of the stem 23 of each hanger is provided, just above the eye 24, with a short, forwardly projecting lug 27,- which is perforated to receive one end of a type bar restoring spring 28, the other end of the said spring being connected with the underside of the associated type bar 16 at about its longitudinal center. The bearing walls 21 are held in a fixed relation to each other by a shouldered rivet 29, the ends of which are inserted in perforations near the bottoms of the bearing walls while the hanger is in process of being folded or shaped into its final form. After the shouldered rivet29 has been dropped into place, the bearing walls are pressed toward each other until they are substantially in parallelism. Each type bar 16 is provided near its, rear end with a perforation 30 into which a pivot 31 with conoidal ends is driven or pressed, and the type bar pvot 31 is thereafter inserted in the conical arin s 32 which have been previously forme in the side walls 21 of the hanger, the latter having sutlicient spring or -give to allow of the seating of the pivot, without permanently altering their set. The ends of the shoulderedr rivet are then headed, or, as it is termed, up-set, the bearing walls being thusl brought into a fixed relation as previously determined by the length of the rivet 29. It will be noted upon an inspection of Fig. 4 that vthe body portion or the distance between the shoulders of the shoulin the type bar bearing. One reason for employing a shouldered rivet is that this form of -rivet is more conveniently headed in the lhanger than is an ordinary rivet of uniform diameterthroughout, which would be liable to drop 'iit of the hanger before the heading" operation was performed. The method of assembling each type barof the rear set with its associate hanger 33,

which with its fellows composes the rear or inner series when mounted 1n the segment 19, is the same as that just described for the forward hangers 20. fin-inspection of Figs. 5 and 6 will disclose certain differences be tween the two forms of hangers,.however. The eye 34, ywhich is provided in the twoply depending shank or stem 35 for the purpose of receiving the stem of a headed set screw 36, whereby the hanger 33 is secured to the segment 19, is in this case formed near the upper end of the said shank 35. Furthermore a lug 37 for the type bar restoring spring 38, is formed on the right hand ply of the shank 35, below the eye 34 and near the end o f said shank, and the said lug 37 is longer 'than the lug 27 of the/hanger 20, sor that when assembled in then/iachnehthe ends of said lugs are' in substantiallyfthe same vertical plane as best appears in Figs. 1 and 7. It will also be noted that vthe hanger 33 is not provided with a part corresponding to the rearward portion 26 of the type bars'are bent or recessed near their pivots so thatthe -rear barsf/will clear the hangers of the forward set.

In assembling the hangers'upon the segment 19, the rear set or seri s composed o hangers 33 are secured against the surfacev of the side or face 39 of the said segmenty by the headed screws 36, the stems of which pass through the eyes 34 and are screwed into holes 40 in the segment, the said holes being tapped to receive the said set screws. The front or forward series composed of the hangers 20 are secured to the front face 'of the segment by set screws 25, which pass through the .eyes 24 and screw into tapped holes 41 inthe segment. The set screws 25 are longer than the' set screws 36, since the mareo will be remembered, are double stood that after the ty Je bars and hangers are thus -in place, the ormer are connected lin the usual manner with their associate .,is adequately depressed the type bar is actuated to swing' it to the printplane rlinlirs 14, which extend over the "series of lset through of all t e type bars of both series. Y be further noted that the form and open seginentand are connected as has been previously described with the key levers 5 by the sub-levers l0, sothat when a iinger hey corresponding ing position, machine.

rThe curved openingofsegment 19 con formato an arc of a circle, the center whereofis approximatel the printing point on as is common in this style of the platen. It wil lbe noted on an inspec tion of Fig. 2 that the centers of the holes 40 are in an arc of a circle of which the printing point isalso the center;y that the centersof-the 'holes el are in an arc of a greater circle7 struck about the same center; and thaty the said holes'of the two sets or l series are staggered relatively. to each other,

a statementvwhich also applies to the two the' said holes to secure the sets or series of hangers in place.

`The position of the segment 19 with relation to theA printing point on the platen 4 and the relative depths of the two series of hangers `are such that a plane passed the pivots of the forward series of ars would be parallel to a vertical vpassed through the printing line on the platen, (said last named plane being indicatedfin Fig. 1, by the dotted line er) and would :be the same distance from such a plane aswould be a similar plane'passed through the'pivots ofthe rearseries of type bars,r which latter plane would also be parallel to the other two; in other words, the printing point is equidistant from the pivots 1t will disposition of the hangersis such that when they type 'are assembled on the segment they are in two @Walls of any hanger in the forward series, except, 'of course, in the case of the end hangers, overlap one wall of each of the hangers at either side of it in the rear series;

( that by means of this overlapping or staggered arrangement of the hangers in respect of each other,

a broader bearing is secured for each type bar than would beA possible with a single series of hangers on the segment'19; that the securing screw of each hanger of the rear series passes between the .Shanks 23 of the adjacent hangers of the screws, soY that all forward series and does not interfere with said forward hangers or their securing of the hangers are sepascrew's which are screwedV intov together,

inating with those rately adjustable and anyone may vbe re-1 moved or replaced or rassembled upon the machine without in any way disturbing any other one; that the construction admits of a of the type bars adjacent to it7 both the latter bars being pivoted in hangers ofthe rear sefries; and that the hangers near the ends o der that the connection between each type bar and its associate key lever may be Vertically arranged, thus adording more room land enabling relatively wider hangers to be used near the ends of-each series than are used inv theY neighborhood of the center. of each series. Moreover it, will be seen that I provide a full complement 'of typebar hangers arranged in two segmental rows, one row being behind the other, the adjacent arms of adjacent hangers of each row vbeing close the adjacent arms of adjacent hangers of the rear row being opposite the spaces between the hanger arms of the for- Ward row and the adjacent hanger arms of the front row being opposite the spaces be- Atween the hanger arms of the rear row, the type bars beinggpivotally mounted in the hanger arms of each row, the hanger arms of the front row of hangers lying between the pivots and the type bearing ends of the type. bars of the rear row, and the type bars of therear i'ow'being formedto arch or reach over the tops or free ends of adjacent hanger arms of the front row; that the type bar hangers in one row or set alternate with those ofthe other row `or set; that the type bars of the two rows when in normal po* sition are alternately arranged; that the hangers are formed or arranged with their hanger arms projecting upi Yardly and in the direction of the printing point; that the Shanks or stems of the two rows of hangers are provided with eyes for the passage of the securing screws, said eyes being arranged in two arcs, the eyes in one arc alterof the other; and that a set' of substantially horizontal pull links are pivotally comilec'ted at their forward ends to the type bars of the two rows forward of the type bai' pivots, the rear ends of said pull links being pivot-ally connected to a set of sub-levers which in turn are operatively each series are spaced wider apart in ore than does the corresponding type of either as the number of forms or series or bcth mightbe varied and still be within the scope of this lnventlon, when considered from certain aspects thereof. i
